CVE-2026-122132 Details
Description
go-chi chi 5.2.2 through 5.5.0 contains an open redirect vulnerability in the RedirectSlashes middleware that allows attackers to redirect victims to external hosts by embedding tab characters in request paths. Attackers can craft links with a URL-encoded tab, which browsers strip from the 301 Location header and resolve as a protocol-relative URL, bypassing the fix for CVE-2025-69725.
A open redirect vulnerability has been identified in the go-chi chi router, specifically in versions 5.2.2 through 5.5.0. The issue resides within the RedirectSlashes middleware, where improper input validation allows attackers to redirect users to external sites. By embedding tab characters in request paths, attackers can craft links that, when processed, strip away the tab and resolve as a protocol-relative URL. This bypasses previous security measures implemented for CVE-2025-69725.
Users can update to go-chi chi version 5.2.4 or later, where this vulnerability has been patched.
